Light hydrocarbon refined and purification technology is an important component of the petroleum chemical industry. The research of light hydrocarbon refined and comprehensive utilization is important to improve added-value of light hydrocarbon fractionation products, the actual application of distillation theory, and the refining of saturate hydrocarbon products and the light hydrocarbon fractionation product processing. Light hydrocarbon is a mixture of low-carbon saturated hydrocarbon which has respectiv...
